The present invention will be described in more detail below with reference to the drawings of the embodiments. However, the present invention is not limited to the drawings as long as the gist thereof is not exceeded. 1 and 2
FIG. 2 is a plan view showing the configuration of an embodiment of the bag with a connector of the present invention. 3 and 4 are views for explaining an example of a connector attached to the bag with a connector of the present invention, in which (a) is a side view and (b) is a plan view.

The bag 100 with a connecting tool shown in FIG. 1 is constructed by applying a bag of a four-way seal type, and the side edges of the laminated films 1 and 1'on the front and rear wall surfaces are sealed with side seals. Heat seal with the parts 2 and 2, and insert a cylindrical connector 50 formed of a plastic molded body and having a liquid passage 53 in the center thereof at one corner of the upper part of the bag, and at the base side thereof. The connecting film thermal bonding part 3 on both sides of the laminated film 1,
The sealant layer 1'is heat-sealed and fixed, and the upper part of the bag including the outer periphery thereof is heat-sealed and sealed by the seal pattern of the upper seal portion 4, and the cut line 8 is used as the bag opening means. The notches 9 and 9 at both ends are provided in the upper seal portion 4 so as to pass through the tip of the connector 50 or its vicinity. In addition, bag 1 with connection tool
The bottom edge of 00 is heat-sealed by the bottom seal portion 5, but since this portion is used as a filling port for the contents, it is an unsealed opening before the contents are filled, and the contents are filled. It will be heat-sealed later. When the filled contents are used, such a bag 100 with a connecting tool connects a tube or the like to the connecting tool 50 and supplies the content to a desired position via the tube. For that purpose, the illustrated bag 100 with a connector is usually used upside down. Such usage is the same for the bag 200 with a connector shown in FIG. 2 below.

The cut line 8 may be an opening instruction line by printing or the like, but it can be more easily cut by using a half-cut line of an easy-opening means or a lamination of a uniaxially stretched film on an intermediate layer of a laminated film. You will be able to open it along line 8. Further, the connector 50 may be a simple cylindrical molded body, but it will be described later with reference to FIG. 3 or FIG.
By making the shape as shown in Fig. 3, the connection of the tube or the like can be more easily and surely fixed, and the bag is less loaded when the connecting tool 50 is attached to the bag, and thermal bonding is easy. It can be performed stably, and the appearance can be improved.

By adopting such a configuration, since the bag 100 with a connector has a large opening at the bottom, the contents are easily filled from this portion, and the bottom seal portion 5 is heat-sealed to seal it. be able to. Since the connection tool 50 is attached by thermal bonding so as to be enclosed inside the end edge portion of the bag 100, it is not necessary to attach a cap or the like, and cost reduction and productivity improvement can be obtained, and Since it is not contaminated from the outside, it is also hygienic. Further, since the connector 50 having hardness is not exposed to the outside of the bag, the connector may be damaged during transportation,
It is also possible to prevent other bags from being damaged by the connecting tool, simplify the packaging, and reduce the packaging cost.

Further, regarding the gas barrier property of the bag 100, since the connector 50 is not exposed to the outside, the connector 5
It is possible to impart excellent gas barrier properties and improve the storability of the contents without being affected by the material of No. 0 and the like and by the constitution of the laminated film. When the filled contents are used, the notch 9 is used to tear the upper seal portion 4 of the bag along the cut line 8 to easily open the vicinity of the tip of the connector 50. Since the liquid passage is opened to the outside, a tube or the like can be connected to surely supply the content to a required position.

Next, the bag 200 with the connecting tool shown in FIG.
In the structure of the bag with connector 100 shown in FIG. 1, the connector 50 is attached by heat bonding so as to be sealed inside the heat seal part at the edge of one corner of the upper part of the bag. The sealing pattern of the upper sealing part 4 for changing the direction to be directed obliquely outward and upward and heat-sealing the upper part of the bag including the outer periphery thereof is connected to the connector 5 as shown in the drawing.
The mounting portion of 0 has an inclination along the base portion of the connection tool 50, and the other portions are heat-sealed by changing to a pattern for laterally heat-sealing the upper end edge portion with a predetermined width,
Along with this, the cut line 8 of the opening means of the bag 200 and the notches 9 and 9 at both ends thereof are provided so as to be changed obliquely so as to pass through the tip portion of the connecting tool 50 or its vicinity, and the bag 200 An enlarged seal portion 6 is provided at a corner portion on the side opposite to the side on which the lower connection tool 50 is provided, and a hanging hole 7 is provided in the enlarged seal portion 6. Except for the changes described above, the bag 100 is formed and configured in the same manner as the bag 100 with a connector shown in FIG.

In this case, the filling port for the contents is not particularly limited, but it is possible to use the bottom seal portion 5 of the edge portion excluding the enlarged seal portion 6 in the lower portion of the bag 200 on both sides of the filling device. Is preferable because the bag 200 can be easily opened by holding the bag with a chuck or the like. Therefore, the bottom seal portion 5 is an unsealed opening before filling the contents, and heat seals after filling the contents for sealing. Further, the hanging hole 7 is shown as a circular completely punched hole in the drawing, but when the contents filled in the bag 200 are used,
It just needs to be used by inserting it into the hook of the stand,
In terms of strength, it is preferable that the portion having a hook or the like has a radius R, but it can be provided in any shape such as an elliptical shape or a horseshoe shape. Further, the hole itself may be a hole which is punched all around, or may be a hole having a cut line in which a connecting portion is partially provided. Rather, the hole formed by the score line is preferable in terms of productivity because it does not generate punch residue and does not require a device for removing punch residue. Such hanging holes 7 are provided as needed, and may be omitted if unnecessary depending on the application.

By adopting such a structure, the bag 200 with a connector has a narrower filling port for contents, but there is no particular problem, and the contents can be taken from the unsealed bottom seal portion 5. It can be easily filled and heat-sealed after filling. Then, the attachment direction of the connector 50 attached to the upper corner portion of the bag, the seal pattern of the upper seal portion 4 including the outer periphery thereof, the cut line 8 as the opening means of the bag 200, and the notches 9 and 9 at both ends thereof.
By changing the forming position of the above as described above and providing the hanging hole 7 as the hanging means of the bag 200,
The following effects can be obtained.

That is, since the area of the heat-sealing portion for attaching the connecting tool 50 can be minimized, the filling capacity of the bag is less reduced and the laminated film of the bag can be effectively used. . When the connection tool 50 is attached to the bag 200 by heat bonding, the strain generated in the laminated films on both sides of the connection tool 50 is easily released, wrinkles and curls can be prevented from occurring, and the appearance is improved. You can In addition, the cutting line 8 for opening the bag 200
Since the length of the opening is short, the opening operation can be performed more easily. When the filled contents are used, since the hanging hole 7 is provided as a hanging means for the bag 200, the bag 200 can be easily hung and used on a hook of a stand or the like. Also, at this time, the connection tool 5
Since 0 is naturally located at the bottom, the residual amount of contents can be minimized and the contents can be effectively used without waste. Also, except for the above changes,
Since it has the same configuration as the bag 100 with a connecting tool shown in FIG. 1, it is possible to obtain the same working effect as the effect described in the bag 100 with a connecting tool shown in FIG.

Next, FIGS. 3 and 4 are views for explaining an example of a connecting tool to be attached to the bag with a connecting tool of the present invention. In each drawing, (a) is a side view and (b) is It is a top view. The connection tool 51 shown in FIG. 3 has a liquid passage 5 at the center.

Further, it is possible to more easily connect a tube or the like to the connector 51 in a rubbing manner. When such a connecting tool 51 is inserted between the laminated films on both sides of the bag and heat-bonded and attached, the laminated film is heat-bonded from both sides of the connecting tool 51 along its outer periphery. It is necessary to heat seal the laminated films that are abutted with each other so that there is no seal omission on both sides, and the operation requires precision, but the connector 51 itself can be manufactured at low cost.

The connecting tool 52 shown in FIG. 4 is the same as the connecting tool 51 shown in FIG. 3 in that a liquid passage 53 is provided in the center, but the upper side of the liquid passage 53 is different. The inner peripheral surface of the (tip side) is provided with a thread groove 55 having a shape corresponding to the thread groove provided on the outer circumference of the end connector such as a tube connected to the connector 52, and the shape of the outer peripheral surface of the connector 52. To
The cross section is changed to a shape in which both sides are curved and constricted like a lid.

By adopting such a structure, the work of heat bonding when the connection tool 52 is heat bonded to the inside of the bag is facilitated, and the stability of heat bonding can be improved. In addition, the tube or the like can be connected more reliably because the tube 52 or the like can be fixed to the connecting tool 52 with a screw type.

The connector as described above can be easily manufactured, for example, by injection molding of plastic. Also, as for the material thereof, in addition to polypropylene, polyethylene, polyester or the like can be appropriately selected and used according to the material of the sealant layer of the laminated film of the bag.
